Samsung's Galaxy S21 was just announced last week and while pre-order deals abound, the phone won't actually be shipping to consumers until the end of the month.
However, that hasn't stopped the teardowns from coming and our first look inside the Galaxy S21 comes courtesy of PBKReviews. Popping off that new plastic back reveals a few interesting changes underneath the hood (via Neowin).

Before we delve inside, the move to a plastic back for the Galaxy S21 is somewhat controversial for those that view a glass or metal back as a sign of a premium device. While the adhesion method remains the same and obviously gives the back a strong and resilient feel when attached, once removed it's easily bent and twisted. However, durability on the phone should be all that matters.
Despite the shift to a plastic back, the Galaxy S21 is slightly heavier than its predecessor, which is less surprising once you get a look inside the densely packed internals. The Galaxy S21 relies on a multilayered board design like the Galaxy S20 to reduce overall size while still delivering that large 4,000 mAh battery.
One potentially important change was the shifted speaker alignment when compared to the Galaxy S20. The S21 follows the Galaxy S20 FE placement at the top of that stack and includes foam balls to allow for greater separation and enhanced volume. The onboard audio on the S20 FE impressed in our review, so we'd expect the same from the Galaxy S21.
A couple of other notable features are Samsung's continued use of 3D graphite pads as a cooling method for the Snapdragon 888 chipset. With the Galaxy S20, some models relied on this method while others used more traditional copper plating options. It's unclear if Samsung has made a full transition now or if this was simply the luck of the draw for this teardown.
Finally, the Galaxy S21 appears to be a step forward in terms of repairability versus the Galaxy S20. He fully disassembled and reassembled the phone without difficulty, something that was not possible with last year's model. We'll be curious to see if iFixit has similar findings when it weighs in with its repairability score. One would hope that could potentially yield to at least slightly reduced repair costs, rather than encouraging replacement over repair.
